they look rigid and feel motionless
No because some are wiggly and jiggly and they move around by having very soft and flexible cell walls. Also, every cell wall is different for a reason. One reason is that different animal and organisms have different body parts.
Cellulose
plant cell walls are made of cellulose, which makes them rigid
the cell walls box like shape
Plant incorporate cellulose into their cell walls, which give them a rigid structure.
a thick, rigid membrane of cellulose fiber.
Lignin is a type of polymer found in the cell walls of plant cells that provides support and structure for the plant- it makes them rigid.

Collenchymatous cells have rigid cell wall
yes, they do
Plant incorporate cellulose into their cell walls, which give them a rigid structure.
Plant cells have chloroplasts and cell walls, which animal cells don't have.
The cell wall makes plant cells rigid.

They do not seem more rigid, they are more rigid! They both have cell walls. Many eubacteria, the bacteria you are most familiar with, have cell walls of peptidoglycan. Plants have cell walls made of interlocking cellulose.
Plant incorporate cellulose into their cell walls, which give them a rigid structure.
Each plant cell has a rigid outer layer called a cell wall. Animal cells do not have this structure.
Animal cells lack rigid cell walls and chloroplasts.
